@futurebird I mean, I'm an engineer, int pi=3
@ehproque @futurebird I'm an astronomer. Let's call it ten for now...

As in 16//5=3

@futurebird a comment
@futurebird in all seriousnessness, the use of "floor divide" implies the result is rounded towards negative infinity, in contrast with "trunc divide" , which implies rounding toward zero, an important distinction when one operand turns out to be negative. Now here's a question: in your favorite languages, which way does integer divide behave? Does the language definition even require a particular behavior? (C90 and C99 for example call it "implementation defined". )

@futurebird I used to call it integer division until I learned that at least in Python it doesn't actually return an int.
Now I just call it The Thing That Looks Like It Does What I Need But Better Stay Away From.@martok this operator has returned an int since it was added in Python 2.2, so this seems weird?

@futurebird Comment?

@futurebird Jokes aside, is it a floor or a towards-zero like the awful C "division" operator? That would affect proper naming a lot.

@jhominal Only if both arguments are int. If either is float, the result is float even if its value is by definition int-ish.
I still think this violates the Principle of Least Astonishment, that's why I just don't use it anymore. int(a/b) is not that much more typing.

@futurebird nobody knows! There's like a zillion ways to do it because there isn't something like a

* floor divide@futurebird Years ago I got offered "show your Python skills" quiz on LinkedIn and the answer to this question was given as "integer division". I was so furious I put in a complaint. It is, of course, "floor division". And Python-style modulus is the One True '%' operator –C's remainder can get in the bin.

no no no THIS is "hand crafted" ... only the finest pi made of the most dubious loops.
import random
import mathinside=0.0
resolution=60000
for i in range(resolution):
x,y = random.random(),random.random()
if math.sqrt(x*x+y*y)<1:
inside+=1
pi=4*inside/resolutionprint(pi)

importing math feels very goofy. I should write a square root finder to avoid that. How do those go? It's like newton's method I think.

@futurebird @yonder @ehproque Newton's method converges wonderfully quickly, so it's often a good place to start. I believe that CORDIC algorithms can also do square roots (although I haven't seen or derived one myself) -- those can be nicer for implementation if you don't have an FPU (or are building one), because they tend to be all about adds and bit-shifts and not much else.
CORDIC only generates one digit per iteration, though, whereas Newton doubles the precision each time.
-
um... not really. What do you do? load a math library?
I mean, how much pi do we need? Just type out ten decimal places and make it a global.
@ehproque @futurebird i need more pi

Can random.random() be stuck in a constexpr to do that at compile time or did someone rightfully shoot down the idea of compile time nonsererminism?

@economia @fucinafibonacci va beh è mesi che chiedono soldi.
Facciano un po come vogliono, blocchino l'elettrico (che tanto non mi posso permettere ( ndr)) io ho ancora qualche tanica di gasolio agricolo in garage.

Se mai doveste passare o fermarvi a #mérida e vi va di mangiare un buon pasto vegetariano, vi suggerisco questo locale, lo "Shangri-La".
Ho preso un ottimo burrito con formaggio, seitan e verdure, seguito da crocchette di funghi in salsa di carote e champignons ripieni di radicchio, cipolla e formaggio.
Poi, 1 dolce alla banana e cioccolato bianco che a differenza di altri dolci spagnoli non ho trovato stucchevole. 21 €
Opzioni vegan.

@ramin_hal9001 Thanks for the suggestion. I am *really* trying to stick with gnome mobile for now but if/once I am finally broken then Phosh is the next UI I will try :)
I did do profiling, and when the bug happens >90% of my sampling was in the JS runtime. I reported my findings here: https://gitlab.gnome.org/verdre/gnome-shell-mobile/-/issues/70
Sadly no solution in sight yet, but would love to have more eyes look at this!

@justsoup normally it's fine, but once or twice a day it gets in a state where gnome-shell uses 100% of a CPU core. It does not let go until the process is restarted (relog or reboot). It'd be nice if it auto-rebooted when it happens honestly, the biggest thing with this is the battery life drain.
